Abstract

We designed a supramolecular complex consisting of a dipicolylamine copper complex with an azobenzene group and phenylboronic acid-modified cyclodextrin for adenosine 5′-diphosphate (ADP) recognition in water. Evaluating its phosphate recognition ability through UV–vis and induced circular dichroism spectroscopy demonstrated high selectivity and a large binding constant for ADP in water. Further investigation into the recognition mechanism suggested that the high sensitivity is due to the formation of a supramolecular complex through a combination of four weak interactions.

二聚胺-铜(II)/苯基硼酸修饰环糊精包合物新型ADP传感器的制备与表征

我们设计了一种由偶氮苯基二聚胺铜配合物和苯基硼酸修饰的环糊精组成的超分子配合物，用于在水中识别腺苷5 ' -二磷酸（ADP）。通过紫外-可见光谱和诱导圆二色光谱对其磷酸盐识别能力进行评价，表明其对ADP具有高选择性和大的结合常数。对识别机制的进一步研究表明，高灵敏度是由于通过四种弱相互作用的组合形成超分子复合物。

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
